Optics
Most rangefinders will offer magnification of some sort in the form of a monocular (some are available in a binocular). The magnification typically ranges between 5 and 8 power. The quality of the optics will vary with the quality of the rangefinder, and again the more expensive models offer far superior optics clarity and magnification than do the cheap models.

When it comes to selecting one of the many laser rangefinders on the market, perhaps the first thing you want to look for is its potential range and application. Some rangefinders also use "modes" so that you can use it effectively in all kinds of terrain and weather. The potential range also varies as many are capable of accurately reporting the range of an object up to 2,000 or more yards. Whether you need one when you’re out golfing or are competing in an athletic, outdoor sport that allows you to use one, laser rangefinders can certainly be a huge advantage for any of these applications.

Golf rangefinders are the rage amongst both amateur and professional players, which is a far cry from the days when it was first introduced. Then, its use was limited to a few professionals and amateurs with money to spare. But as with all things in golf and in life, rangefinders eventually became an essential part of a golfer’s arsenal to shoot the ball into the hole.
